Bought these for my 01 yukon xl. Popped right in. Working good as of now. I live in Hawaii and the time it took to get here was not bad at all. Still a customer of 1A Auto with no complaints

The kit was excellent. However, it was a misfit for the vehicle it was ordered, and I take responsibility for the misorder. It would have been helpful if the description of the coil highlighted its method of mounting. This would have prevented my error. Although the error was mine, no issue was encountered when return and refund was requested. This is invaluable. Especially since errors randomly occur when its not possible to do a comparison prior to ordering a part.
As advertised. 1AAuto comes through for me again!

2000 GMC Sierra 1500 LTE 5.3 V8. Products arrived on time, and were as advertised. Installation was occasionally challenging (not unexpectedly) but the parts from 1A Auto were just right. So far so good!

My truck went from having misfire in cylinder 8, then multiple misfires. Codes instantly cleared after installing new coil packs, wires, and spark plugs. Truck still runs strong at 230K. Thank you guys!
Perfect

Ignition coils!!

I wouldn't recommend to purchase coils from here. They were cheap quality and made incorrectly. I was forced to use them because my car needed them and I had to make it work. But the coils kept falling apart on the magnetic side and not only that but they weren't made to fit my car like the car look up said it would fit. Not happy wouldn't recommend

Coils fit great and worked good after installing only problem was with the plugs , had to cut , modify them so they can connect to the spark plugs , or they would not connect and keep coming out , after that they work great

This kit is correct for the V8 motors out of those vehicles with the square style coils.
